To amplify David Brodie's answer:

   The string "$Revision:  3.1 $" is probably supplied by
CVS, the Concurrent Versioning System, and that literal in
that line of the program changes every time the Python
module is checked into change control.  You're really
looking at a slick way to communicate between CVS and the
module user.
